above a steam-heated revoluble drum or a y chest, andthe articles tobeironed arefcaused by posedtransversely or the rolls. In order to'vavoid the use ot such s tringsjand the like/tor j properlyv advancingWOl, flexibleistrip?I er .fingers have been associated `witlrthe LettersPatentf.:[:]:1,186,640 and iny my prior U. SrLetters Patent: #1,7l0,980.Y

The present invention'relates more particu: larly to an improved form ofstripper `'nger suitable for useas aforesaid; andit has forj its objectto provi-de a moreeiicientstripper nger and one whichwill readilyyieldwhen Y n encountering an abnormal `v`obstruction i and thus avoidbecoming enmeshed with the work passing through the yironing machine. Aurv ther object ot' lthe invention resides in theA provision of meansJfor introducingv a pre-fr 'determined resistance in the finger andwhich 39V must Arst be overcome before'l the linger will Y yield to passan obstruction, thus insuringy against too frequent resetting .of thefingerv v which would result'if the yielding vaction were f asjdelicateas required withthe ordinarystrippertinger arrangement.'V A stillfurtherobject of the invention resides vision of a substantial andruggedfstripper* finger and one which may be inexpensively manufactured.f

ityA of the novel fingers are arranged longi- .tudinallyfor1 a vroll asset lforth inthe atore'- 1 padding ormatted padding, is frictionallyheld thereon by being wound over the roll said Letters Patent; and eachindividual n ger comprises a blade of resilient material se#v curedlrigidly to a-support yat vits innerend, while yto its tree outer endlthere is hingedly attached a tip member designed tov collapse toward theback of its carrying finger upon:

in the pro-` j Incarrying out the invention, a multiplie-f' 1930. SerialNo. 446,208..

is introduced toprevent collapse of theftip -untilsaid resistance hasbeenv overcome as,

for example, in'theprovision of yieldable ears at the sides of the tipand embracing the ad-v jacent side edges of the finger end. These earshave inwardly directed projections adapted for engagement with the saidside edges and over which the edges must thus ride before permittingcollapse of the tip. Lateral wings, also, are arranged to project atright angles from the sides of the tip substantially at its outer end;and the same'k have rounded edges ,adapted normally; to

guide and direct the'workbetween rolls as well as to ride smoothly upona roll when said tip collapses.

'The nature ot the-invention, however, will best be understood whendescribed in connection with the accompanying.;drawings, in which: j i fK Fig. 1 is a fragmentary transverse .sectionV through an ironing rolland associated steam] chest, showing the application of the novelstripper members thereto.

Fig. 2 is aA similarview illustrating a strip-y per member in collapsedcondition; Y

Fig. 4 is a rear elevation of a novel stripper nger, on an enlargedscale; Fig. 5 is a longitudinall section thereof; and F ig.. 6 is anenlarged transverse section taken on the line 6 6, Fig. 5.

Referring to the drawings, 10 designates i one or a plurality ofrevolubly actuated ironing rolls such as are utilized in an ironingAmachine, for example of the chest type, the Y said roll being journaledfor rotationabove a steam-heated chest 11, the surface of whichimmediately beneath saidy roll is generally concave to secure greaterironing contact, A cloth covering 12, usually hair padding, wool withlapped portion 13 toA insure retention of the cover A on the rollsurface. Guard or binder members 14care also associated with the roll toprevent the lapped portion workthe underlying cloth portion;

S. Letters Patent, Serial No. l121,892. The saidstrippers are of narrow thin blades of flexiblen material suchas bluetemperedribbon steel, and haye a securing arm at the inner end.
